신장이식은 환자의 삶의 질을 높이고 거의 정상적인 사회생활을 가능하게 함으로써 말기신부전 환자의 3가지 신대체 요법(혈액투석, 복막투석, 신장이식) 중에 가장 효과적이고 각광받는 치료법이라 할 수 있다. 최근 들어 의료기술과 의학의 발달로 신장이식의 성공률은 과거에 비해 비약적으로 높아지고 있으며 국내에서도 점차 신장이식수술을 받는 환자가 증가하고 있으나 서울이나 다른 대도시에 비해 의료환경이 열악한 중소도시나 지방의 병원에서는 아직도 시행하지 못하고 있는 형편이다. 이에 저자들은 경북 최초로 자체 의료진에 의해 고혈압과 말기 신부전으로 동국대 포항병원에서 혈액투석을 받고 있던 32세의 남자환자에게 부인으로부터 신장을 제공받아 신장이식을 성공적으로 시행하였기에 문헌고찰과 함께 보고하고자 한다. Kidney transplantation is the preferred treatment modality for many patients with end-stage renal disease (ESRD), because it offers improved quality of life over both hemodialysis and peritoneal dialysis. Patients who do well after transplantation generally report improvement in vitality and freedom to return to the style of life that they experienced before their progression to ESRD. Recently, the success rate of kidney transplantation is greatly being increased as the surgical technique and immunosuppressive drugs are developed. Kidney transplantation is also popular in Korea which has good result. But, until now the general hospitals which are located at small city can't try the kidney transplantation because they don't have proper facilities and experts. We firstly experienced a case of kidney transplantation in a 32 years old man with hypertension and chronic renal failure at KyoungBuk province. So we report this case with references.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces tenuipes Jocheon-1. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. Paecilomyces tenuipes Jocheon-1 cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes Jocheon-1 was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDHis comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The cDNA encoding Pt-GAPDH was expressed as a 37 kDa polypeptide in baculovirus-infected insect Sf9 cells. The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA.

Fungi belonging to the Paecilomyces spp. have recently been used as food and herbal medicines in Korea and are greatly popular as commercially available powdered supplement or dried fruiting body. Despite this acceptance and its use, little is known of the genes related to its reactive agents. Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces spp. based on the previous identification of ITS1 and ITS2 at the molecular level and collected from Jocheon Miryang, Korea. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes- Jocheon was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDH is comprised of 1,014bp encoding 338 amino acid residues.

The purpose of this study was to investigate the kinematic variables of the lower extremity during the Soccer In-step shooting motion. To conduct an investigation, five soccer players(skill group) and five students(less-skill group) in the high school were participate in this study. They were videotaped using three video cameras with the frame rate being 60㎐. This data was then reducted to 3D coordinates using the DLT(direction linear transformation)method. It was concluded that; Medio-lateral(X) displacement of the skill group was larger than that less-skill group and antero-posterior(Y) displacement of the skill group was smaller than that less-skill group. Velocity transfer of the skill group was more effectiveness than less skill group. The sequence of the maximal joint velocity of the kicking leg was the hip, knee, and ankl joint. It is considered very important that the sequence of the laximal joint velocity is from the proximal to the distal in order to increase the foot velocity at the impact. Trunk angle of the skill group was smaller than that less-skill group. And then ankle joint angle of the skill group was larger than that less-skill group.

이경구,이준호,권용욱,정태융,심희영,이상익 관동대학교 의과대학 의과학연구소 2005 關東醫大學術誌 Vol.9 No.1

Tension-free vaginal tape(TVT) has been widely used in the management of stress urinary incontinence(SUI), and has been applied to urge incontinence (UI). We evaluated and compared the outcomes between SUI and UI for patients who had undergone TVT. Patients were categorized into SUI(33 patients) and UI(26 patients). Before treatment, we asked about LUTSs using female bladder questionnaire. And we asked about sexual function. After treatment, the same questionnaires were repeated. During the postperative period, the objective and subjective success rate were evaluated. For operation outcome results, in SUI group there were 29 cases of cure (87.9%)and 2 of improvement(6.1%), and in UI group there were 20 cases of cure(76.9%)and 3 of improvement(11.5%) (p>0.05). The operation satisfaction rate of patients was 90.9% in SUI group and 84.6% in UI group(p>0.05). Improvement of sexual satisfaction occurred in 6(20.0%) of SUI group, and 3 (18.8%) of UI group, respectively(p>0.05). The objective success rate, satisfaction rate and sexual satisfaction of SUI patients did not significantly differ from the women with UI. Also, these results shows that TVT procedure improves some LUTSs in both groups. We consider the TVT procedure to be an effective treatment not for stress urinary incontinence but also urge incontinenece.

본 논문에서는 퍼지-신경회로망 동정모델을 이용한 간단한 제어기 설계방식을 제안하였다. 제안된 제어방식은 입력신호와 관련이 없는 시스템함수 f(x)의 동정은 퍼지-신경회로망을 이용하고, 입력신호와 관련된 함수 g(x)는 동정하지 않고 임의의 실수로 놓는 동정모델을 이용하여 제어기를 설계하였다. 제안된 방식의 특징은 기존의 동정을 이용한 제어기 설계방식보다 간단하고 계산량의 감소로 속응성이 개선될 수 있다. 제안된 제어방식의 유용성을 입증하기 위하여 직류 서보전동기를 제어대상으로 위치제어에 대하여 시뮬레이션 하였다. In this paper, we propose a simple controller design method using the fuzzy-neural network identification model. In the proposed control method, the identification for the system function f(x) make use of the fuzzy-nural network, and the system function g(x) replace an arbitrary real number, with no identification, and then designed a controller using the identified information. The characteristics of the proposed method can be improved control performance and can be reduced calculation over a conventional identification method. And then it applies to DC Servo Motor as an controlled process. And then it take a simulation for the position control, so that verify the usefulness of the proposed control method.

이희구,이홍수,이인애,최용경,최인성,정태화,김길현 이화여자대학교 생명과학연구소 1995 생명과학연구논문집 Vol.6 No.-

Hybridoma producing monoclonal antibodies reactive with the β-chain of interleukin-2 receptor (IL-2R) were generated from mice immunized with a synthetic peptide of 19 amino acids. The synthetic peptide constitutes strongly hydrophilic region of extracellular domain of the IL-2R molecules(residues 32-50) as revealed by hydrophathy plot analysis. Hybridomas were screened by ELISA using Hut102 cells and the synthetic peptide as antigenic moiety, and by miasuring the binding activity of antivodies to the Hut102 cell surface that was monitored by a flow cytometer. The antibodies were further screened by their inhibitory effect against the interaction between IL-2R and interleukin-2(IL-2). Antibodies were further characterized by immunoprecipitation followed by autoradiography to reveal that the antibodies recongnize the 75 KD protein molecules expressed on the Hut102 cell surface and human peripheral blood mononuclear cells(PBMC) shich confirms the antigenic moiety to be β-chain of IL-2 recepter molecules.

In this paper, we designed a nonlinear controller using a new identification method of neural network. The method proposed in this paper performs, for a nonlinear plant with unknown parameters, identification with using a neural network, and then a stable nonlinear controller is designed with those identified informations. The advantage of the proposed control method is simple to design a controller because, for unknown nonlinear systems, we used the identified informations and design parameters are positioned within a negative real part of s-plane. In order to verify excellent control performances of the proposed method, we compared with a conventional neural network control method through a lot of simulations with one link manipulator.
